Understand the procedure for paying your French tax...

Income tax for 2018 will be paid on income earned in 2017 until the new withholding tax system is put into place.

You will need to file a tax return around May. Unless you have opted for monthly payments, you will need to make payments on 15 February and 15 May 2018, each equal to one third of the amount of the previous year's total income tax. The final payment is due after the actual assessment is received (normally in the late summer/early autumn) for payment by 15 September.

If this is your first year of residency in France, your income tax won’t be due until September of this year.
